Not blooming! New to hydrangeas!
I live in Perth West Australia - it is a mediteranean climate, cool winters and hot summers, mild rain (no frost snow etc). We have just moved into our new house and at the home open there were blooming hydrangeas against a south wall (darker side of the house down here) doing really well and flowering. When we moved in July (winter here obviously) the previous owner had pruned them back very severely to a foot or so high. It has recovered with lots of blood and bone, seaweed liquid fertilizers and lots of water - it doesn't get any direct sunlight here only shade. It hasn't bloomed though, despite lots of lush green foliage at least three foot high. Any ideas on how long to wait for blooms? Do I also have to cut it back next winter like the previous owner did? I am new to gardening so thanks to everyone for reading / responding to this in advance.
